By disconnecting the lmttom ofthe casing, 717 from the producer may be removed Without breaking any of the 11min joints of the plant.

Near the top of the upper portion of t yroducer there is formed a. trough, g, extom iiig horizontally around the apparatus too projecting into the vaporizing chamber, Water to be vaporized is delivered-to this i with 9. mun er of grooves, 1', or the like roo which the Water overflotan s.
